The user wants me to build a single-page 2048 game in one self-contained HTML file. Let me plan this out: 1. **HTML Structure**: Game board, score display, win/lose modals, reset button 2. **CSS**: Grid layout for tiles, animations for sliding and merging, styling for different tile values (2, 4, 8, etc.) 3. **JavaScript**: - Game logic (tile movement, merging, spawning) - Keyboard controls (arrow keys) - Score tracking - Win condition (2048 tile) - Lose condition (board full, no moves possible) - Smooth animations Let me build this comprehensive game in one file.
I'll build a fully functional 2048 game with smooth animations, score tracking, win/lose states, and keyboard controls.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
